Introduction

The IS4320-41 ScanKey™ Laser Scanner is a wearable, fully automatic, laser

scanning device complete with keypad and LCD. Since the IS4320-41 is

positioned on the back of the hand, operators can scan data quickly and easily.

This “hands free” scanning increases operator efficiency and work

productivity. Traditional hand-held scanners require the operator to interrupt

the work flow by picking up the scanner and returning it to its stand. With the

ScanKey, not only are both hands free to perform other tasks, but the operator

is always ready and able to scan.

In addition to quick scanning, ScanKey’s 17-button keypad enables bar code

data to be manually entered. All information is displayed and then transmitted

to the host device. Portable data terminals and computers requiring RS-232 or

Light Pen Emulation communication are common host devices.

Metrologic’s HandSet™ IBM® compatible software program and simple bar

code menus make the ScanKey easy to program. Host- programmable features

can be displayed at the user’s prompt.

Two-way host communication is also a feature of the RS-232 version

ScanKey. Among other host-programmable features, operators can use either

long-range or short-range activation, establish which bar codes are to be read,

and command a “good scan” beep indicator. These features can be

accomplished through the command processing set.

The IS4320-41 ScanKey autodiscriminates all standard bar codes, including

bar code types with alphanumeric characters. Specifically assigned sequences

are provided to translate the standard numeric keys for alphanumeric data

entry.

2

Theory of Operation

The scanning process begins once the infrared (IR) device located behind the

window senses an object in the scan field. The IR sensor is active as long as

power is applied to the unit. When the IR sensor detects an object, the display

reads "READY TO SCAN" and the cursor flashes to show that the laser is

"ON." When the laser decodes a bar code, the scanner transmits the data to the

host system and then "beeps" to indicate the decoding is complete. The IR

sensing range can be programmed for two ranges.

Short Range Activation: The IR signal initiates the scan process if it senses

an object anywhere from the face of the window

out to approximately 4" to 7".

Long Range Activation: The IR signal initiates the scan process if it senses

an object anywhere from the face of the window

out to approximately 9" to 13".

If the object is removed from the field during the scanning process, the laser

turns off.

However, if the object stays in the field, the laser remains on for up to 2.5

seconds trying to detect another bar code. If the scanner does not detect a bar

code, the laser turns off. To reactivate the scanning sequence, remove the

object and present another.

If the same symbol stays in the field after a successful scan, the laser stays on

for approximately 4 seconds and then turns off. This prevents unintentional

reads of the same bar code. To read the same symbol more than once, remove

the object from the scan field for approximately 1 second and then present the

symbol again.

Scanner Installation

Important Note: To maintain compliance with applicable standards, all

circuits connected to the scanner must meet the requirements for SELV (Safety

Extra Low Voltage) according to EN 60950.

1. "Power off" the host system.

2. Connect the communication cable to the host device.

3. Plug the scanner cable to the communication cable.

Note: The pin assignments for the scanner cable are listed on

page 29.

4. "Power on" the host system.

Note: When the scanner first receives power, diagnostic prompts

are displayed then the scanner "beeps." "READY TO

SCAN" appears on the display.

Configuration to the Host System

Before the scanner ships from the factory, the factory programs the scanner to

a set of default parameters. However, many functions of the scanner can be

modified to meet your individual needs. The scanner’s parameters can be

modified by entering the program mode and scanning the appropriate bar

codes that appear in the Programming Guide. For a list of various parameter

settings, refer to the Default Settings section in this guide. To modify the

settings, refer to the Programming Guide.

Audible Indicators

The scanner provides sounds to signal certain conditions. To change the

volume (three settings are available) or turn the beeper off, refer to the

Programming Guide section: Beeper Tones.

One Beep When the scanner first receives power, diagnostic prompts

are displayed and then the scanner "beeps." After that, each

time the scanner successfully reads a bar code, it "beeps."

Razzberry If, upon power up, the scanner emits a razzberry tone, then

Tone the scanner has failed diagnostics.

Note: The scanner can be programmed to emit a razzberry

tone when the timeout occurs during communica-

tion between the host and scanner. Refer to the

Programming Guide section: Audible Indicators for

Communication Timeouts.

Three Beeps When the scanner enters the program mode, it beeps three

times then the message "PROGRAM MODE ENABLED"

appears. When the scanner exits the program mode, it beeps

three times and the message "READY TO SCAN"

reappears.

Note: The scanner can be programmed to emit three beeps

when the timeout occurs during communication be-

tween the host and scanner. Refer to the Programm-

ing Guide section: Audible Indicators for Commun-

ication Timeouts.

7

Visual Indicators

The following display messages show the scanner status.

READY TO SCAN The scanner is operational and ready to scan a bar

code.

PROGRAM MODE Scanning the Enter/Exit Program mode bar code

ENABLED alternately enables and disables the program mode.

When the program mode is enabled, this message is

displayed.

MAKING KEY ENTRY Keypad data is being entered. (This message dis-

appears when the ENTER key or the CLR key is

pressed).

8

Entering Data Using the Keypad

The display clears with the first key pressed and "MAKING KEY ENTRY"

displays on line two of the LED display. Key-in numbers of the bar code, then

press enter. The scanner will "beep" to indicate that the data was sent to the

host computer.

To make changes while keying in the numbers, use the up and down arrow

keys. The up arrow acts the same as the space bar on a computer keyboard. It

places a space at the current cursor position and increments the cursor to the

next character position. The down arrow acts the same as a backspace key on a

computer keyboard. It places a space in the previous character position and

deletes any character that might be there thus becoming the new cursor

position.

Although only numeric keys are shown on the keypad, alphanumeric charac-

ters can be entered by first pressing a Function key then a Numeric key.

F1 Upper left-hand character set

F2 Upper right-hand character set

F3 Bottom left-hand character set

Example: Press F1 then 7 to get A (F1 + 7 = A)

Press F2 then 3 to get @ (F2 + 3 = @)

Press F3 then 4 to get L (F3 + 4 = L)

Mode Descriptions

Mode 1: Metrologic Default Mode*

This mode’s main function is to display and transmit and is not suitable for host

prompts. In this mode scanned-in data will be displayed on line 1 of the LCD display

and truncated to 20 characters. The first 20 characters are displayed on line 1, the 2nd

line is cleared with the 21st character and will display the remaining characters entered.

The entire length of the bar code will be transmitted up to and including the 40th

character. *Selectable prefix/suffix options are not displayed on the LCD display. They

are however, transmitted with the bar code.

ScanKey Mode 2:

This mode’s main function is to transmit only. The host system controls the LCD

display. Line 1 of the display is blank, all scanned-in data and keyed-in data are

transmitted to the host system, nothing additional is displayed. This mode is used for

complete host control. It can be used to display customized prompts.

ScanKey Mode 3*:

Line 1 is used for the host prompts. Line 2 is exclusive to the user and will display the

data. Scanned-in data displayed on line 2 will be truncated to 20 characters. If a host

prompt is being displayed on line 1, it will be cleared to allow for the 21st and

subsequent characters to be displayed. The entire length of the bar code will be

transmitted up to and including the 40th character. *Selectable prefix/suffix options are

not displayed on the LCD display. They are however, transmitted with the bar code.

Mode 4: INTACTIX/INTERCEPT Program

This mode’s main function is that it is to be used with the INTACTIX/INTERCEPT

program. Scanned-in data will be displayed on the line 1 of the LCD display and

truncated to 20 characters. The entire length of the bar code will be transmitted up to

and including the 40th character. When using the keypad, the keys are transmitted to

the host system via a make/break sequence and the key assignment is simultaneously

displayed on the LCD display.

Command Processing Set

The COMMAND PROCESSING SET is a set of predetermined commands to enable

or disable some useful scanner functions. The lists on the following pages represent

these sets and the protocol for using them. All commands for modes 1, 3 and 4 begin
